Clinical evaluation of disilicate and zirconium in dentistry

Abstract

In recent years there has been a huge leap forward in the prosthetic field, primarily linked to the ability of the clinician to exploit new technologies and new materials. In fact, the application of CAD/CAM techniques which are already well known, for example, in engineering, has allowed us to spread the use of new ceramic materials, making the spread much easier. Principally two materials have greatly changed dental practice: the zirconium and lithium disilicate. The purpose of this publication will be to investigate the characteristics of these two materials and their clinical applications, trying to rationalize the selection criteria and operational protocols. In fact, if, on one hand, therapeutic results that were unthinkable until a few years ago are possible, on the other hand, these materials require a thorough understanding of their characteristics in order not to run into avoidable failures.
